The amazing thing about Squaretalk is they were able to take something that must be highly configurable, sophisticated and complex and turn it into super compatible and clear software. In addition, their onboarding and customer success teams went out of their way to integrate the solution with the business tools that we are using (including some that it was not designed for) and made sure that everything, to the smallest resolutions, works perfectly.
